Ronald Cron 40170d9516 tests: Rename test driver entry points 
Rename test driver entry points to
libtestdriver1_<name of the Mbed TLS entry point>.

This aligns with the renaming of all Mbed TLS APIs
for the test driver library (that will be put in place
in the following commits) to avoid name conflicts
when linking it with the Mbed TLS library.
